Peak Fresh Produce bags slow down the natural aging process of fruit and vegetables, preserving both the freshness and the life of your produce. Peak Fresh Produce Bags remove ethylene gas (ripening gas) given off by produce and anti-fog treatment reduces moisture levels on the film surface to more than double existing storage life of produce under refrigeration. All PEAKfresh® mineral impregnated MAP (Modified Atmosphere Packaging) films are certified for packaging organically grown produce (International Federation of Organic Agricultural Movements). PEAKfresh® films are FDA approved, comply with current EU Directives, and are approved by Swiss, Austrian, Canadian, Australian, and New Zealand Authorities. Bags can be re-used for up to two months.
